Application filed January 1923.

To all whom t may concern.'

Be it known thatI, dor-IN F. OConnon, a citizen et the United States, residing at Chicago, in the county o1 Cook and State ot Illinois, have invented a certain new and useful Improvement in Side Bearings for Railway Cars, ot which the following is a iull, clear, concise, and exact description, reterence being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in side bearings for railway cars.

One object of the invention is 'to' provide a simple and etlicient gravity centering side bearing and one especially adapted 'tor-attachment to the body bolster ot a car.

Another and more specific object ofthe invention is to provide a side bearing of the type specied composed ot three pieces, nested together, and held in assembled relation when attached to the car.

In the drawings forming a part of this specilication Fig. 1 is a. transverse sectional view through the body and truck rholsters of arailway c ar showing in side elevation my improved sidebearing. Fig. 2^is a vertical sectional view through the body and truck bolster showingmy improved side bearing Ain end elevation. .And Fig. 8 is a vertical sectional view taken substantially on the line 33 of Fig. 1 showing certain parts in elevation.y

ln said drawing, 10 indicates the lowerportion of a body bolster and 11 the upperv portion ol' a truck bolster oit' "a railway car, my improved side bearing being shown as attached to the body bolster.

The improved side bearing comprises, broadly, a supporting member A, ya swinging retaining member B and an antitriction roller bearing C.

The supporting member A, comprises a-y downwardly projecting head 12 and upper laterally extending arms 13 andy 111.' The supporting member A is secured to the bodyk bolster 1() by rivets 15, or any other suitable means. In the upper tace of thesupporting member A is formed a depression .16 to provid'ea curved bearing surface 17, and the downwardly projecting` head 12 of the supporting member is provided with a conveX lower bearing surface 18 adapted to coact with the anti-friction roller C; y

The retaining member B comprises a pair of substantially T-shaped plates 19 con# Serial No.' 610,757.

integralv therewith. The journal member20 extends through the depressed portionlG` of the supporting member and'is adapted to turn on the bearing surface 17 when the body and truck bolsters are'separated a'suiicient distance to lift the rollerk Cout of Contact with thertruck bolsten Each of the plates 19 isprovided kwith a downwardly extending relatively rbroad arm 21, and laterally projecting side arms 22 at its upper end.k As clearly shown inFig. 1, the upperends ot the plates 19 are cut away to provide downwardly and outwardly inclinedy 'faces 23 extending from the center of said retaining member to the outer ends of the arms 22. In this connection it will benoted that the upper ends of the plates 19 and the upper side of the cylindrical ournal member 20 are normally slightly `spaced 'trom the lowery face of the'body bolster10to prevent actual contact therebetween. The, outer 'ends .of the upper tacesot the arms 28 serve asstops by'engagement with the lower face of the body bolster 10, toy `limit the swinging moveinent of the'carrier B. The opposed `innery faces of the plates 19 are provided with U- shaped ribs-24 thereby deiining roller trunnion yreceiving recesses 25 which are open at the upper sides to'permit the trunnions of the roller to be inserted. The plates 19 are valsol provided with vertically 'extending f Theanti-frictionroller C isprovided with integral trunnions 26 rotatably supported in the recesses 25, and is adaptedy to roll between curvatureA of the bearing faces 2'? ,of the the upper taceot the truck bolster11 and 'i the yconvex bearing face 18 of the head 12 of the supportingmem'ber A. The center .of

ribs 24jis so spaced withv reference to thef axis of the cylindrical journal member that thecarrier B 'when the body bolster 10 is i `moved upwardly with reference to the truck bolster 11. f f

- In assembling my improvedside bearing,

the roller C is `inserted between they plates 19 vot the carrier B and the trunnions 26 passed into the'recesses 25 through the Open upper ends thereof. It will be noted that when the roller has thus been inserted in the carrier, the same is retained in position by the sidewalls 19 and the U-shaped ribs 2e thereby holding the same in position and permitting the removal thereof only in a vertical direction. The carrier B is then assembled with the supporting member A by passing either of the arms 13 or 14E of the supporting member through the space between the cylindrical journal member 2O and the roller C and seating the journal member 2O in the depression 16 of the supporting` member A. The supporting member A is then xedly secured to the body bolster 1 0 by means' of the rivets 15, thereby holding the three parts forming the side bearing in permanently assembled relation. In this connection it is pointed out that the journal member is confined between the lower face of the body bolster and the supporting member A and that the plates 19, which are formed integral therewith, prevent lateral displacement of the retaining member, thus holding the same in permanently assembled lrelation with the supporting member. The roller C is held in permanently assembled relation with the retaining member by engagement of the upper portion of the roller with the convex bearingv face 18, whereby upwardmovement of the roller to an extent to permit disengagement of the trunnions from the recesses 25, is prevented. As the swinging movement of the retaining member is limited, by the ends of the arms 9.3 coming in contact with the lower face of the body bolster, to an extent to prevent the roller from passing beyondthe ends of the convex face 18, said roller cannot be disengaged from the retaining member without removing the latter from the supportA.

In the voperation of my improved side bearing, as the body bolster 10 and the 'truck bolster 11 rotate. relatively and approach each other, the anti-friction roller C will roll between the upper face of the truck bolster and the convex face 18 of the supporting member, the pressure being transmitted through the'member A to the body bolster. During this operation the retaining member B swings outwardly with the roller.

rolling action will continue until the retaining'member B reaches one of the extreme positions where movement is arrested by the arms 23 engaging with the body bolster 10.' @ne of said extreme positions is shown by dotted hnesin Fig. 1. Upon removal of the pressure from the side bearing member and the separation of the body bolster and truck bolster, the supporting member A willmove upwardly independently of the retaining member B a slight distance, until the journal member 20. is supported by the lcurved bearing face 17, Ywhereupon the retaining member will act in the manner of a pendulum and swing back to normal position, due to the force of gravity and thereby automatically center the roller without the aid of springs or yother relatively frail means.

l have herein shown and described what l now consider the preferred manner of carrying out my invention, but all changes and modifications .are contemplated that come within the scope of the claims appended hereto. y
